Temperature sensors some AMD Ryzen programmed to display values with an offset of +20°C
AMD told more about one particular AMD Ryzen. Basic temperature sensor (T Control or tCTL) some models reported value is overstated by +20°C. According to the manufacturer, this is done intentionally to allow the upper threshold of all models to the same value and unify the algorithm of operation of the cooling system.
Among processors, which were presented first, the temperature offset at +20°C reported by the sensors AMD Ryzen 7 1700X and 1800X. The required correction of the readings will run diagnostic programs and tests automatically, and yet to know the real value, it is enough to subtract an offset from the reported results. In the case of model Ryzen 7 1700 do not need to, because the sensor and informs the actual value.
